Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example one
Fig. 2 is a schematic flow chart illustrating a calculation method for transmitting load by interference coupling according to an embodiment of the present invention. The execution subject of the embodiment is a computing device for transmitting load by interference coupling, which can be implemented in software or hardware. As shown in fig. 2, the method includes:
and S11, establishing a containing piece model according to the containing piece, and establishing a contained piece model according to the contained piece.
The structure of the containing part and the contained part can be regular cylindrical or irregular cylindrical.
Specifically, when the containing part and the contained part are regular cylinders, a cylinder with the diameter of 80mm at the matching part and the length of 100mm can be directly selected as the contained part, and a sleeve body with the outer diameter of 100mm, the wall thickness of 10.1mm and the length of 40mm is selected as the containing part.
When the containing part and the contained part are regular cylinders, models of the containing part and the contained part can be respectively established according to the actual sizes of the containing part and the contained part; or respectively establishing the containing piece model and the contained piece model according to the maximum interference magnitude or the minimum interference magnitude. For example, three-dimensional modeling software is used to establish the containing part model and the contained part model respectively.
And S12, performing statics finite element analysis on the containing part model and the contained part model, and determining a support reaction force curve at the boundary of the containing part based on the contact type and the boundary condition of the containing part and the contained part.
The contact type is friction, and the contact type can be set by a user in a self-defined mode, and meanwhile, the corresponding friction coefficient and the penetration tolerance are set.
The boundary condition can also be set by the user. When the calculated load is the maximum axial force value, setting the boundary conditions as follows: one end face of one side of the fixed contained piece is provided with the axial displacement of one side of the contained piece. When the calculated load is the maximum torque, the boundary conditions are set as: one end face of the contained part is fixed, and the angular displacement of one side of the contained part rotating around the axis is set. Specifically, the displacement may be set in a step-loading manner. For example, the sub-step setting of the finite element statics software can be opened, and the minimum number of sub-steps should be greater than 10 steps.
Specifically, the containing part model and the contained part model can be introduced into a finite element statics module for statics finite element analysis, and the containing part and the contained part are divided into grids and solved; and extracting the support reaction force at the boundary of the containing piece to obtain a support reaction force curve. From theoretical mechanics, the magnitude of static friction is equal to the external acting force, and the maximum value of the static friction is equal to the dynamic friction. The magnitude of the kinetic friction force is equal to the product of the positive pressure and the friction coefficient. Therefore, the dynamic friction force value is obtained through the support reaction force value in the finite element statics module by considering the relative axial movement of the applying containing piece and the contained piece.
And step S13, acquiring the load transmitted by the interference coupling structure from the support reaction force curve.
Specifically, a constant value of the ordinate value in the thrust-reaction force curve may be extracted, and the constant value may be used as the load transmitted by the interference coupling structure.
Therefore, in the embodiment, the containing piece model is established according to the containing piece, and the contained piece model is established according to the contained piece; carrying out statics finite element analysis on the containing part model and the contained part model, and determining a support reaction force curve at the boundary of the containing part based on the contact type and the boundary condition of the containing part and the contained part; the load transmitted by the interference coupling structure is obtained from the support reaction force curve, so that the load transmitted by the containing part and the contained part with regular structures can be calculated, the load transmitted by the containing part and the contained part with irregular structures can be calculated, and the structural shapes of the containing part and the contained part are not limited.
In an optional embodiment, step S12 specifically includes:
step S121, responding to the first user operation, and acquiring the contact type of the containing piece and the contained piece as friction.
Wherein the first user operation is for setting a contact type of the containing member and the contained member. Specifically, a setting interface may be generated, and the user may complete the setting of the contact type between the container and the accommodated part by triggering the virtual switch at the preset position of the setting interface.
Step S122, in response to the second user operation, acquires a boundary condition.
Wherein the first user action is to set a boundary condition. Specifically, a setting interface may be generated, and the user may complete setting of the boundary conditions of the containing part and the contained part by triggering the virtual switch at the preset position of the setting interface. In addition, the set boundary conditions are also related to the calculated load. When the calculated load is the maximum axial force value, the boundary conditions are set as follows: fixing one end face of the contained piece, and setting one axial displacement of the contained piece; when the calculated load is the maximum torque, the boundary conditions are set as: one end face of the contained part is fixed, and the angular displacement of one side of the contained part rotating around the axis is set.
And step S123, dividing the containing part and the contained part into grids, and solving.
In step S124, the reaction force at the boundary of the container is extracted to obtain a reaction force curve.
Specifically, when the calculated load is the maximum axial force value, the support reaction force at the axial displacement position of the containing piece boundary is extracted to obtain a support reaction force curve. When the calculated load is the maximum torque, the support reaction force of the angular displacement amount of the containing piece boundary rotating around the axis is extracted, and a support reaction force curve is obtained.
In an optional embodiment, after acquiring that the contact type of the containing piece and the contained piece is friction in response to the first user operation, the method further comprises:
in response to a third user operation, a friction coefficient and a penetration tolerance are acquired.
Example two
Fig. 3 is a flowchart illustrating a calculation method for transmitting load by interference coupling according to a second embodiment of the present invention. This embodiment describes the present invention based on the containing member and the contained member being regular cylindrical. As shown in fig. 3, the method includes:
and S21, selecting a cylinder with the diameter of 80mm and the length of 100mm at the matching position as an accommodated part, and selecting a sleeve body with the outer diameter of 100mm, the wall thickness of 10.1mm and the length of 40mm as an accommodated part.
And S22, respectively establishing the surface bodies of the containing part and the contained part according to the axial symmetry principle and introducing a finite element statics module.
And step S23, arranging the matching parts of the sleeve body and the shaft to be in contact so as to transmit axial force and positive pressure, wherein the contact type is friction.
Wherein the coefficient of friction is set to 0.1. The permeation tolerance type was chosen as a value with the size set at 0.01mm.
Step S24, setting boundary conditions as shown in FIG. 4, wherein the boundary 1 restricts the Y-direction displacement to be 0, and the rest degrees of freedom are released, and the boundary 2 sets the Y-direction displacement to be 1mm at the right boundary of the sleeve body, and the rest degrees of freedom are released to simulate the relative movement of the containing piece and the contained piece in the axial direction.
Moreover, the direct single-step loading of 1mm displacement does not necessarily capture the following maximum support reaction force, i.e. it cannot be determined how much displacement is properly loaded. So the displacement is set by adopting a step loading mode. Opening the sub-step setting of the finite element statics module, the initial sub-step number is set to 15, the minimum sub-step number is set to 10, and the maximum sub-step number is set to 30.
And step S25, dividing grids, and dividing smaller grids on the contact surface.
And S26, solving.
In step S27, the reaction force at the boundary 2 is extracted to obtain a reaction force curve.
As shown in fig. 5, a reaction force curve is obtained at this time due to the step load displacement.
In step S28, the ordinate value of the reaction force curve is changed from small to large and is finally constant at a value of 97990N. The value at this constant is the maximum axial force value transmitted for this interference coupling.
Therefore, the axial force is calculated to be 101283N according to the GB/T5371 formula method. The finite element result is 3289N different from the theoretical calculation result, and the difference is 3% of the theoretical calculation result. The results of finite element are influenced by mesh accuracy and contact stiffness in accordance with the expected results and are slightly less than the theoretical results. Improving grid accuracy and contact stiffness reduces the difference from the theoretical result, but consumes more computing resources, actual engineering calculations usually have a greater safety factor, and a difference of 3% is acceptable. The results of finite elements are consistent with theoretical results from actual numerical proportion. It can be shown that the finite element loading scheme described above is reasonable.
EXAMPLE III
Fig. 6 is a flowchart illustrating a calculation method for transmitting load by interference coupling according to a third embodiment of the present invention. This embodiment describes the present invention based on the case and the accommodated member being irregularly cylindrical. As shown in fig. 6, the method includes:
and S31, respectively establishing a containing piece model and a contained piece model by using three-dimensional modeling software.
The modeling can be carried out according to the actual machining sizes of the containing piece and the contained piece, and the modeling can also be carried out according to the maximum interference or the minimum interference.
And step S32, importing the containing part and the contained part model into a finite element statics module.
And step S33, setting the contact type of the containing piece and the contained piece as friction, and setting the friction coefficient and the penetration tolerance according to the actual situation.
Step S34, setting boundary conditions: one end face of one side of the fixed contained piece is provided with the axial displacement of one side of the contained piece.
And step S35, adopting a step loading mode to set the displacement.
And opening the sub-step setting of the software, wherein the minimum sub-step number is more than 10 steps.
And step S36, dividing grids.
And step S37, solving.
And S38, extracting the support reaction force at the axial displacement boundary of the containing piece to obtain a support reaction force curve.
And S39, extracting a constant value of the ordinate value, namely the maximum axial force value transmitted by the interference coupling.
Specifically, if the ordinate does not have a constant value, it indicates that the axial displacement of the container in step S34 is set too small and should be adjusted to be large; if the constant value of the ordinate of the curve is unstable and the numerical value fluctuates, the process returns to step S33 to readjust the set permeation tolerance value.
In addition, for the calculation of the interference connection torque of the irregular cylindrical fitting piece, the calculation steps are basically the same as the calculation steps of the method, and the maximum torque which can be transmitted by the interference connection can be obtained only by modifying the axial displacement in the corresponding step into the angular displacement rotating around the axis.
